Rolling bearing description
Dec 26, 2016

Characteristics of rolling bearings:

(1) small and stable coefficient of friction, starting is easy. Ball bearing f=0.001-0.002, f=0.001-0.003 roller bearing, needle f=0.002, f=0.003 thrust ball bearing thrust roller bearing f=0.004.

(2) the axial size small.

(3) the small radial internal clearance and preload.

(4) the lubrication convenience, easy to maintain.

(5) some bearings can also accommodate circumferential and radial forces, the structure is simple.

(6) disadvantage: poor ability to withstand impact and radial dimensions, noise at high speed, short life.
